Description
Technical field
This utility model relates to auto parts and components mounting technology field, specifically be a kind of fit structure turning to casing body and rack bush.
Background technology
Existing machinery turns to the design of machine to see Fig. 1, housing coordinates with rack bush, coordinated with the boss of rack bush by the bore hole groove on housing carry out spacing, this design is when housing produces, need to process this locating slot by one bore hole road sequence, rack bush needs when fitting into housing to use frock to install simultaneously, rack bush is installed the situation of putting in place and cannot be judged by range estimation, have part assembling defective, need for this to design a kind of can ensure that the qualified processing simultaneously of assembling easy turn to casing body and rack bush fit structure.
Summary of the invention
This utility model break through the difficult problem of prior art devise a kind of can ensure that the qualified processing simultaneously of assembling easy turn to casing body and rack bush fit structure.
This utility model devises a kind of fit structure turning to casing body and rack bush, including housing, rack bush, O and back-up ring, it is characterized in that: described housing is set in tooth bar outer rim, back-up ring, rack bush and O it is provided with between housing and tooth bar, the side of back-up ring fits with the positive stop lug boss of tooth bar, the opposite side of back-up ring is arranged with rack bush, and the outer rim of rack bush is embedded with two parallel O.
The profile of described back-up ring cross section is " L " shape.
This utility model compared with prior art, reduces the processing cost of housing, improves the axiality of housing and rack bush, rack bush can be directly loadable into when assembling, without by frock, improve the qualification rate of rack bush assembling, reduce the time needed for assembling.
Accompanying drawing explanation
Fig. 1 is the installation diagram of prior art.
Fig. 2 is schematic diagram of the present utility model.
Seeing Fig. 2,1 is housing, and 2 is rack bush, and 3 is O, and 4 is back-up ring, and 5 is tooth bar.
Detailed description of the invention
In conjunction with accompanying drawing, this utility model is described further.
See Fig. 2, this utility model devises a kind of fit structure turning to casing body and rack bush, including housing 1, rack bush 2, O 3 and back-up ring 4, housing 1 is set in tooth bar 5 outer rim, back-up ring 4, rack bush 2 and O 3 it is provided with between housing 1 and tooth bar 5, the side of back-up ring 4 fits with the positive stop lug boss of tooth bar 5, and the opposite side of back-up ring 4 is arranged with rack bush 2, and the outer rim of rack bush 2 is embedded with two parallel O 3.
The profile of this utility model guide ring 4 cross section is " L " shape.
By back-up ring, lining is carried out spacing in being embodied as, increasing the contact surface of back-up ring 4 and housing 1, improve intensity, the housing processing herein can be done directly by a cutter, not only eliminating the process time of bore hole, part axiality also can be guaranteed；Rack bush, when assembling, can be directly loadable into, it is not necessary to by frock, assembly qualified rate can be improved.
